Before proceeding to a. more scription of my invention, it nust detailed deb e clearly understood that the plates contactingwith the flexible bag may be of any desired form or shape, and preferably will have the contour of the bag to wh lied. There may be ornamental design, cut

The pressure applied by this resilient cam member, 21, while in contact with the bulging portion, 15, is transmitted to the bag between the plates until the entire contents is expelled from the bag. To prevent the flow of liquid from the mouth of a bag not provided with a stop er a clamp or clip,,25, of any suita le form, which will fit the'bag and close its mouth; to prevent any outflow from same, is applied.

Having thus described my invention, I claim as new and desire-to secure, by Letters Patent: g
